What Eiahn said. =) Looks like I'll do Glenumbra next Tuesday, October 6, per what I am seeing.
So this is done with all EP characters like Eiahn said. EP is our home alliance even if a lot of us have random alts in the others or were living there and then came here to Gaiscioch and started playing new EP toons to play with family. =)
To do Cadwell Silver. You have to complete the storeline and have Cadwell pop you to Glenumbra. Nothing else required. You can even get there non-vet if you manage to kill off Molag Bal before being a Vet.
To do Cadwell Gold. You have to do the main story lines - listed in Cadwell's very own section on your Journal (J) and then have him zap you to Auridon. You will definitely be VR6 or better by the time you hit this if you do everything in Silver besides Cadwell's stuff with how leveling works now.
Also, as Eiahn noted these are to clear all that crazy group stuff - Dolmen's, World Bosses, and the wonderful Public Dungeons. Even if you have all of them done in a map, it's fun to see what wild ride I take you on and have fun playing with family.
BTW, it is a wonder I only missed one night in September the way things went from Labor day until this past weekend!
